基于GIS的地质数据库系统:研究现状和发展趋势

The Geologic Database System with GIS: Research Status in Quo and Development Trend

有效地存储、管理、交流、进而充分利用正日益增多的地质资料和数据 ,离不开功能强大的数据库管理系统 .然而 ,地学数据显著的空间特征和复杂的结构属性又不能简单运用常规的数据库管理系统进行表述、处理 .地理信息系统 (GIS)技术 ,以其对空间数据强大的储存查询和分析处理功能而鲜明地区别于普通管理信息系统 ,正适合于对复杂的地球空间数据进行采集、储存、分类、检索查询、刻划表述、以及分析建模 .因此 ,先进的GIS技术与强大的地质数据库系统相结合 ,亦即是 ,基于GIS的地质数据库系统的开发和应用 ,是计算机技术应用于地学研究的发展方向和应用趋势 ,是当今地学发展所必需的基础技术之一 .本文结合我们的近期工作概述了这一新兴领域的研究现状和发展趋势 .

Database management system is a powerful tool for store (accumulation), management, maintenance and analysis of ever-increasing geological data. But it is very difficult to use common data-management technique based on relation database to the geological data because of their distinct spatial features and complex configurations. Newly developed computer technique of Geographic Information System (GIS) is particularly suitable for collection, description, analysis and modeling of spatial data of the Earth. Thus, coupling between geological database system and GIS technique, namely, developing powerful geological database system based on advanced GIS technique is one of the most important techniques for modern geosciences. The present paper, in combination with the authors' up-to-date research, introduces the status in quo and discusses future develop trend in this new field.
